To all whom it may concern.-

Be it known that 1, JOHN O. LINDEN, a citizen of the United States, and a resident of Prophetstown, in the county of Whitside and State of Illinois, have invented a new and Im-- proved Snow Loader and Unloader, of which the following is a full, clear, and exact descr1 tron.

's invention relates to improvements in machines for cleaning snow from streets or roads and loading the snow into a wagon, from which it may be unloaded at any suitable place, theob ect being to provide a machine of this character so constructed that the loading and unloading will be ractically automatic and in which the wor 'ng parts may be controlled from the driver's seat.

Other objects of the invention will appear in the eneral description.

I wi 1 describe a snow loader and unloader embodyin my invention and then oint out the novel eatures in the appended c aims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the figures. Figure 1 is a side elevation of a snowloader and unloader embodying my invention. Fig 2 is a longitudinal section thereof on the line 2 2ofFig.3. Fi .3isap1an. Fi .4isadetail showing a c ain-gearin emp oyed, the same being a section on the ine 4 4 of Fig. 3. Fig. 5 is an end, view of one of the snow-carrier plates, and Fig. 6 is a rear view thereof. Referring to thediawings, 5 designates the wagon box or' bod mounted on the -front wheels 6 and rear w eels 7. The box or body has a solid bottom 8 but the rear end-board is provided-with a discharge-opening 9, and there is an 0' ening 10 at the front of the bot: tom, throug which the carrier-now to be described may pass. This'carrier consists of endless chains 11, movable-along the upper.

side of the bottom 8, and connected to the chains at suitable distances apart are upwardly-extended carrier-bars 12. At the forward portion the chains pass over sprocket- -wheels 13, and at the rear end they en age with driving sprocket-wheels 14, mounte on a shaft 15,'arranged rearward of the, body. On one end of the shaft is a worm-wheel 16, designed to be en aged by a worm 17 for driving the carrier forward in the wagonbody while loading the snow or carryin lit:

toward the forward end of the body. worm 17 is mounted on a shaft consisting of two pivotally-connected sections 18 19, the sectlon 18 being movable upward to disengage the worm 17 from its wheel, as will be hereinafter described. Loosely mounted on itie shaft-section 19 are bevel-pinions 20 21,

e whedl 22 and the other pinion 21 engaging with a smaller gear-wheel 23, these gearwheels being connected to one of the rear wheels of the wagon. The object of this arran ement is to change the speed of movement of t e carrierthat is, in some cases a, slow motion is required, While in other cases the carrier may be moved at a greater speed.

To place either one of the pinions in driving connection with the worm-shaft, I employ a clutch mechanism-that is, the pin- 1011 20 is provided with a clutch-section 24,

designed to be engaged by a clutch-section 25 on a ring 26, mounted to slide on the shaftsection 19, but adapted to rotate therewith. On the forward side of the ring 26 is a clutchsection 27, that may be placed in engagement with the clutch-section 28 on the pinion 21. From the ring 26 a shiftin rod 29 extends forward and connects with t e lower end of a shifting lever 30, ivoted on the vehicle-bod adjacent to the river's seat; On the she.

15 is a pinion 31, meshing with a pinion 32 on a stud extended outward from thevehiclebody, and on this stud is a sprocket-pinion 33, from which a I chain 34 extends to a s rocket pinion 35, loosely mounted on a s eeve 36 whichforms the hub of one of the rear wheels. On this sprocket is a clutch member 37, designed to be engaged by a clutch member 38, slidable on the rear axle, but rotating therewith. The clutch member 38 is provided with an annular channel into which pins from dne member of an anglelever 39 engage. This angle-lever 39 is pivoted on a lug 19,-and from the outwardly-extended portion of the an le-lever a draw-rod 41 extends forward inion 20 engaging with a large gearis thrown into engagement with the clutch member 37 the worm '17 must be at the same time thrown out of gear with ts wheel. For

"this purpose the worm-shaft 18 is mounted in a bearm 43, mounted to slide on a bracket 44, attac ed tothe vehicle-body.

As clearly indicated in Fig. 4, a bolt passes from the bearing 43' and through a slot in said yieldingl bracket 44. Pivotally connected to the bearing is a horizontally-dlsposed member having an angle-lever 45, and the vertically-disposed member of said-lever has a rod connection 46 with the lever 42.

When the snow is discharged into a vehicle-body by the loader, to be hereinafter described, it is preferable to somewhat compress it into cakes or sheets. Therefore I employ a presser consisting of upwardly-divergent endless aprons 47 48, each provided with a series of cross-slats 49. The aprons are mounted on endless chains,.-the chains of the rear apron 47 engaging at the upper portion of sprocket-pinions 50 and at the lower portion with s rocket-pinions 51. The upper portion of t e chains for the apron 49 engage with sprocket-pinions 52 and at the ower portion with sprocket-pinions on a shaft 53, which is mounted on bearings movable toward and from the rear apron and held yieldingly by means of s rings 54. The shafts for the upper sproc et-pinions are mounted in frames 55, extended upward from the vehicle-body, and on the shaft 53 is a inion 56, meshingwith a pinion 57 on the s aft for the lower sprocketinions of the rear apron, and on this shaft 1s as rocket-pinion 58, in which a chain 59 exten s to a drivingsprocket 60, rigidly attached to the rear axle.

I will now describe the means for loading the snow into the vehicle body or box. The loader comprises a frame 61, which is inclined upward an forward and is mounted on supporting-wheels 62, from" the axle of which arms '63 project forward and have down-- wardlly-turned ends for detachabl engaging in soc et members 64, secured to tl ie rear end of the vehicle-body. Brace-bars are connected at their upper ends to the side members of the frame 61' and at their lower ends to the arms 63. Attached to.the lower end of the frame 61 is a curved scraperlate 66,

end of the frame 61 and certain links fornotches 68 for receiving the teeth on sprocket-wheels 69, mounted on a shaft 70, arranged at the lower portion of the frame 61, and on this shaft 70 is a pinion 71, from which a chain 72 passes to the driving-wheel 73, attached to the rear axle. Oncertain of the slats 67 at the ends are upwardly-extended blocks 74, to which upwardly-extended carrierplates 75 are yieldingly attached. These plates are mounted to rock on shafts 76, mounted in the blocks 74, and they are.

held b means of plate-springs 77, extende upwar from the shafts 76 and engaging against the rear sides ofthe plates.

In the operation as the machine moves forward the snow will be scraped up by the scraper 66 and discharged onto the endless carrier, from which the snow will pass to the com ressor. carrier in the vehicle-body may remain stationary, as the clutch-carrying ring 26 maybe in an intermediate fiposition, as indicated in Fig. 4. .When a su cient amount of snow is discharged into the rear portion of the body, the clutch-ring may be moved to place either one of the pinions 20 or 21 into driving connection with the worm-shaft, so that the car rier in the body may move forward, carrying the snow toward the forward end of the body. In unloading the loader may be detached from the vehicle, and then as the vehicle moves forward and the pinion 35 is placed in driving connection with the sleeve 36 through the medium of the clutch-section and the worm 17 detached from its wheel, as beforeother wagon'for scraping up the snow.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
